🦶 Zone 1,2 – Heel Center (Central Calcaneus)

This zone is the center of the calcaneus — the rearward midpoint of the heel, typically the default point of contact in quiet standing.

🔬 Anatomical Role

  • Bears maximum weight during upright standing
  • Primary contact during walking heel strike
  • Directly loads the calcaneal tuberosity
  • No muscle originates or inserts directly beneath

🔬 Muscle & Tendon Support

Structure Type Action Relevance
**Achilles tendon (insertion)** Tendon Transfers calf muscle force Indirect rear support
**Calcaneal fat pad** Tissue Absorbs shock Primary cushioning
**Plantar fascia (central band)** Fascia Passive arch support Contributes to forward support

⚙️ Biomechanical Function

  • Excellent for load-bearing
  • Absorbs impact during heel strike
  • No rotational resistance or torque generation
  • Lacks proprioception detail — low feedback

🧠 Verdict

  • Torque Handling: ❌ None
  • Muscle Support: ✅ Passive only
  • Feedback Quality: ⚠️ Low
  • Stability: 🟢 Very high

🩰 Use in Dance

  • Used for:
    • Heel leads
    • Weight resets
    • Walking or neutral standing balance
  • Not useful for balance recovery or reactive poise

“Zone 1,2 is where weight goes to nap.”

✅ Summary

Zone 1,2 provides superb stability but no torque or feedback, acting like a parking brake for the foot. Great for stillness, but don’t expect action.
